Upcoming

  • Dan Long will serve in the Pacific West Area Office, Albany, CA, as acting Associate Area Director during October. Stewart Wuest will take over leadership responsibilities in Pendleton.


  • Dan Long, John Sulik, and Hero Gollany will attend the American Society of Agronomy meetings in Long Beach, CA during Nov. 2-5, 2014. John and Dan will present the paper “A Yellowness Index for Oilseed Yield Estimation”.

    ARS technician Elizabeth Torres and Washington State University technician Jeanene DeAvila preparing samples for DNA analysis. Kate Reardon hosted Jeanene DeAvila as part of a collaboration with Professor Tarah Sullivan to investigate the effects of soil treatments on fungal and bacterial populations in grape and wheat cropping.


    Hero Gollany and her team performed soil sampling in the long-term conventional tillage, no-till winter wheat–pea cover crop rotation and winter wheat– fallow plots. From left to right, Wayne Polumsky, Patrick Nash, and Joe St. Claire are shown preparing for the next sample extraction.


    Stewart Wuest, Tami Johlke, and Steve Umbarger seeded on-farm test plots in a grower’s field. The test plots received one non-inversion tillage pass the 29th of May, leaving all of last year’s crop residue on the surface. We were successful in placing the seed into moist soil, and we have hopes that it will emerge sooner than the rest of the field where the seed was “dusted in” and is waiting for rain. This region has received very little effective rain so far this fall.

  • Stewart Wuest’s research team is collecting soil samples from experiments in the driest parts of Washington and Oregon’s wheat-growing region. These experiments are designed to determine the optimum timing for initial tillage in the widespread practice of tilled fallow--winter wheat production. Tilling too early reduces storage of spring rains, decreases residue cover, and creates conditions for increased wind erosion and soil crusting.


  • Sally Schneider, Deputy Administrator of Natural Resources and Sustainable Agricultural Systems, and Charlie Walthall, National Program Leader, traveled from Beltsville, MD to learn more about Pendleton’s work in soil and water conservation, and see the facilities and land resources available.



  • Microbiology lab tour with National Program Leaders (left to right) Charlie Walthall, Sally Schneider, Kate Reardon and collaborator Kristin Trippe (USDA-ARS, Corvallis, Oregon).

  • Kate Reardon and Elizabeth Torres hosted post doc Brett Mellbye for lab training as part of a collaboration with Research Microbiologist Kristin Trippe from the USDA-ARS Forage Seed and Cereal Research unit in Corvallis Oregon.



  • Steve Umbarger is seeding winter wheat in the sweep fallow treatment field site, near the Rew elevator, with an IH150 drill.

  • Stewart Wuest, Tami Johlke, and Steve Umbarger seeded winter wheat into summer fallow plots near Echo, OR on 25 September. This location has been very dry for the last three years. The very minimal, one-pass tillage performed at the end of May retained enough seed-zone moisture to germinate wheat. This method leaves lots of surface residue and soil clods, which helps prevent soil from rolling back into the furrow and burying the seed too deep. Our research is designed to see if a minimum tillage summer fallow might out-perform the more intensive tillage used on millions of acres of dryland wheat in the Pacific Northwest.



  • Stewart Wuest is checking the depth of winter wheat seed in a sweep fallow treatment field site, near the Rew elevator.


    Wayne Polumsky processed the bundle samples to determine grain and biomass yield. Hero Gollany will determine harvest index for the long-term research experiments.
